To all whom it may concern;

Be it known that I, HARLAN GEORGE MOATS, a citizen of the United States, residing at Villisca, in the county of Montgomery and State of Iowa, have invented certain new and useful Improvements in Culverts, of which the tollowin is a specification.

My invention re ates to improvements in culverts, and refersparticularly to a culvert composed of segmental cement slabs and the assembling of which may be accomplished by an ordinary laborer or unskilled mechanic.

In common practice it is the usual custom in building cement or concrete culverts to first build a mold or form and then fill this mold with the cement or concrete and allow it to harden and it is one of the objects of my in- ,vention to dispense with the use of these cumbersome molds or forms, and thus make a great saving in. time, labor, and expense.

Another object of my invention 1s the provision of a culvert which can be made in any desired size or shape and shi ped in parts to the destination, where the cu. vert may be assembled with facility and accuracy.

Another object of my invention is the provision cf a device of the character described which will be substantial in construction and practically indestructible, which will be composed of a few simple parts, and which will be practical and efficient in every particular.

" With these objects in view my invention consists of a culvert composed of slabs of cement or like material secured together by means of supporting-rings or collars, means for securing said collars together, facing-walls at the ends of the culvert, and means for se curing said walls to the collars or supportingrings.

Figure 1 represents a side elevation of the complete invention, showing the culvert as it appears when assembled. Fig. 2 represents a longitudinal central sectional view of Fig. 1. taken on the line 3 3 of Fig. 2 looking in the direction in which the arrows point. Fig. 4 represents a side elevation of one of the end sleeves or collars, and Fig. 5 represents a lon" gitudinal elevation of one of the end posts which serve to hold the wall-slabsin position.

Referring to the drawings, the letter A designates the cement or concrete segmental slabs, which may be of any desired size and of a shape to form a circular culvert, as shown, or a horseshoe-shaped culvert or any other dig. 3 represents a sectional view irregular shape, as desired. In order to hold and secure the slabs in position, I provide supporting-rings or collars B, whichare formed with the pair of annular rims C, between which is provided the groove or channel D, in Which the ends of the slabs are adapted to fit. These collars are formed with the integral lugs E on their circumference, and these lugs have the openings l therein in which are adapted to fit the securing bolts or rods G, which rods are secured in place by means of the nuts H or any other suitable means.

If the culvert is of suflicient length to require it, a supporting-ring is placed inter mediate the length of the culvert, as shown in the accompanying drawings; but if the culvert is not of a length su'flicient to require an intermediate support the slabs forming the conduit may be sup orted from the ends only, in which case the s abs will extend from one end support to the other in one solid piece.

It will be noticed that the intermediate supporting-rings are double-faced and are provided with a channel on each face; but the end-supporting rings are provided with a channel only on one (the inside) face J, and the outside face K is flat, and a roove L is formed on the outside diameter 0 the collar for the reception of the end slabs'M. These slabs form a wall or facing for the mouth of the culvert, and the slabs are secured at the ends by the end osts N, provided with a groove or channel to receive the ends of the slabs.

From the nature of my invention it will be understood that a culvert constructed in accordance with my invention may be built of an indefinite length by having intermediate supporting-rings provided atthe proper distances, or if the culvert is not long enough to require intermediate supporting-rings then the slabs may be made in one piece and only have supporting-rings or collars provided at the ends.

ill hen the culvert is assembled, if desired, cement may be placed in the interstices between the slahs, and thus make a practically one piece structure.

From the materials used in the construction of my improved culvert it will be seen that the culvert is practically indestructible and will last indefinitely and is constructed or" so few and simple parts that is may be easily assembled by the most unskilledilabor, thus making it practicable and desirable in every respect.

supporting-collars having annular grooves both faces to receive the ends of formed in the slabs, said collars having integral lugs formed on the circumference thereof,and 1ongitudlnal bolt-rods secured in the lugs and extending the entire length of the culvert.

2. The combination in a culvert, with end collars having annular grooves formed in one face and a oove in the periphery thereof, segmental s abs having their ends engaging the annular grooves, end slabs engaging the peripheral grooves and forming a wall, the

i collars being formed With lugs on the circum-- ference thereof, of longitudinal bolt-rods secured in said lugs length of the culvert.

3. In combination, a culvert comprising and extending the full I end collars having annular grooves in one cured to said slabs, intermediate supporting collars having annular grooves formed in both iacesto receive the ends of the slabs, lugs formed integral on the circumference of the collars, andlongitudinal bolt-rods secured in the collars and extending the entire length of the culvert.

In testimony whereof I afiiri'my'signature in presence of two Witnesses.
